Discovery May Lead to New Crack-resistant Metal Alloys

June 25, 2015

0 Comments

The image shows corrosion of a silver-gold alloy spontaneously resulting in the formation of nanoscale porous structures that undergo high-speed cracking under the action of a tensile stress. It helps demonstrate a discovery by an Arizona State University research team about the stress-corrosion behavior of metals that threatens the mechanical integrity of engineered components and structures.

A new discovery by researchers at Arizona State Univeristy points the way to designing crack-resistant metal alloys with different microstructures. Sometimes looking at something at the smallest scale can lead to solutions to big problems. A recent study into the interactions of metal alloys at the nanometer and atomic scales is likely to aid advances […]

Graphene Quadruples Rate of Condensation Heat Transfer

New research from MIT shows that a graphene layer one atom thick could quadruple rate of condensation heat transfer in generating plants. Most of the world’s electricity-producing power plants — whether powered by coal, natural gas, or nuclear fission — make electricity by generating steam that turns a turbine. That steam then is condensed back […]
